Leontius of Byzantium, not a Church Father, but nevertheless influential in Christology, posited that Christ took the flesh of all humanity. But he took this deified humanity and wrapped it in his divinity--so without a) the divinity and b) the deified nature of the flesh, you would only get a man that had the same physical features. Clones do not have the same exact personality as the one from whom they are cloned, necessarily. Furthermore, maybe all the DNA ascended with him
Interesting speculation though.
